Hi, I completely uninstalled Wine 1.1.42 (current version in Ubuntu 10.04) Code: sudo apt-get remove wine rm -rf $HOME/.wine rm -f $HOME/.config/menus/applications-merged/wine* rm -rf $HOME/.local/share/applications/wine rm -f $HOME/.local/share/desktop-directories/wine* rm -f $HOME/.local/share/icons/????_*.xpm Then I added Wine repository to Ubuntu 10.04 Software Sources. (http://www.winehq.org/download/deb) Now I am running current 1.1.44 version of Wine on Ubuntu 10.04 32bit and Valve's new Steam client seems to be working now! Jesse
